COMBINATION LADLE AND BABBITTING-JIG.

Specification of Letters Patent.

Patented Aug. 31, 1920.

Application filed December 19, 1919. Serial No. 346,009.

articles, it is intended more particularly for` use in babbitting the crank shaft bearings ot multicylinder engines.

ln its preferred embodiment, the invention embraces among other features, a bottom pouring ladle adapted to set directly upon the open tlat side oi' the bearing to be babbitted, a die for placement within the bearing to mold the molten metal to .tit the crank Vshait as said molten metal runs into the bearing, and means to grip and close the ends ot said bearing and prevent the molten metal trom running out of said ends.

Other features will hereinafter appear, and in order that the invention may be fully understood, reference will now be `had to the accompanying drawings, in which:

Figure 1 is an elevation of the device with the jaws thereof in open position preparatory to gripping and closingthe ends of the bearing upon which the device is seated.

Fig. 2 is a vertical central section ot the device withthe jaws closed upon the ends oi the bearing. A

Fig. 3 is .a horizontal section on line III-III of Fig. 2. v

Fig. i is a fragmentary vertical section on line IV-.IV of Fig, 1.

Fig. 5 is a horizontal section on line V-'-V of Fig. 2. l Y j n Fig. 6 is an inverted plan view of the device with the jaws inclosed position.

Fig. 7 is a broken detail perspective view of a valve for controlling the lliow of molten metal from the bottomot the ladle.

Fig. 8 is a fragmentary elevation of a Fig. 10 is an inverted plan view of a `modilied form of the die.

ln carrying out the invention, I employ a ladle 2 having a flat bottom 4 adapted to set directly upon the open flat side ot' that portion of the bearing A formed integral with the engine block. Said bottom 4 has a pair of oppositely-disposed gates G through which the molten metal flows into the bearing A, and a pair of dowel pins .7v to lit within the bolt holes of the bearing and thus hold the ladle in proper position upon said bearing A.

The outflow of molten metal through the gates 6 is controlled by a valve 8, loosely connected to the lower end of a rod 10, so that the two plugs 1l of. the valve 8 may seat squarely over said gates 6. The valve rod l() extends upwardly through a tubular member' 12 and .is provided at its upper end with a knob 1d, whereby said valve rod 10 may be raised to open the valve 8 against the yielding action of a coil spring 1G, abutting at its upper end against the closed end 18 oi the tubular member 12 and at its lower end against a collar 2l) fixed to the valve rod 10.

The lower end of the tubular member 12 is secured tothe upper portion of a yoke 22, iXed to the upper portion ofthe ladle 2. Preferably, the tubular member 12 is threaded into the yoke as shown on Fig. 2, and in orderto prevent it from accidentally unscrewing, a spring washer 24 is interposed between the lclosed end 18 oi said tubular member 12 and a handle 26B having a wire handhold 28. y 1 i `The handle 26fis secured to the upper end of a hollow shaft 30, journaled upon the Vtubular member l2 and extending downwardly to the top of the yoke l22, upon which it is held by the washer 24E pressing downwardly on the handle 26. The lower portion ci the hollow shaft 30 is provided with oppositely-disposed peripheral lugs 32,*pivotally-connected to the inner ends ot links 341 extending in opposite directions and pivotally connected at their outer ends to the upper ends of leversBG, fulcrumed in the biturcated endsolf an equalizing bar 38 extending through the sides of the yoke 22 and provided with a central slot 10 through which the valve rod l0 freely extends. The equalizing bar 38 is free to slide in the yoke 22, for a purpose which will hereinafter appear, but such sliding movement is limited by stops 39 carried by said equalizing bar and adapted to contact the adjacent sides of the yoke 22. The lower ends of the levers 36 are connected by pivots 37 to aws 42, slidable upon a die 44 and having recesses 46 at their upper inner' portions to clear the adjacent sides of the ladle 2 when said jaws 42 are closed against the ends of the bearing A as disclosed on F ig. 2. The die 44 extends loe.- tween the gates 6 and is fixed to the ladle 2 by any suitable means, screws 48 being shown for that purpose. A longitudinal opening 50 is formed in the upper portion of the die 44 to receive the lower end of the ladle 2 (see Figs. 2 and 4). The die 44 is of the same diameter as the shaft to be journaled in the bearings which are babbitted with the device, and said die 44 is of tubular formation to permit air to circulate freely therethrough to keep it relatively cool, so that it will quickly congeal the molten babbitt poured into the space C between the bearing A and said die 44 and thus reduce to a minimum the time required to babbitt all of the bearings of the cylinder block.

ln practice, the jaws 42 are opened in 0rder to pass downwardly at opposite ends of the bearing A upon which the device is lowered until the bottom`4 of the ladle 2 rests upon the open flat side of said bearing and the dowel pins 7 pass lthrough the bolt holes B. This positions the die 44 in proper relation to the bearing A. rlhe jaws 42 are then caused to grip the ends of said bearing A by rotating the handle 26, which, through the intermediacy of the intervening` mechanism, causes the aws to move inwardly, and not only grip the ends of the bearing as above-described but also Vto close the ends of said bearing and thus prevent the molten metal from running out at said ends.` vrlhe valve 8 is then opened to permit the. molten metal to flow from the ladle 2 into the bearing A by engaging the knob 1.4 with two fingers and grasping the hand hold 28 and pulling upwardly on said knob against the actionof the coil spring 16. After the bearing has been babbitted, the knob 14 is released, whereupon the valve S is immediately closed by the action of the coil spring le. The handle 2G is then rotated in a reverse direction to cause the jaws 42, to release the ends of the bearing, whereupon the device is applied to another bearing of the engine block. Should one of the jaws 42 engage the bearing A before its companion, the latter may move into engagement with the bearing owing to the fact that the equalizing bar 8S is free to move longitudinally, as hereinbefore mentioned.

Slotted guides 52 on the yoke 22, prevent the upper portions of the levers 36 from being bent laterally by the links 34 when the hollow shaft 30 is rotated to open or close the jaws 42.

Owing to the rapidity withv which the dee vice hay be operated, all of the bearings of a cylinder block, usually three in number,

can be babbitted before the molten metal in the ladle 2 congeals.

In the modified form disclosed by Figs. 8 to l0, inclusive, the construction is substantially' the same as in the preferred form, as evidenced by corresponding numerals with exponents a ln said modified form the jaws 42iL are slid longitudinally upon the die 44a by hand, instead of being actuated by the mechanism disclosed on the preferred form. In order to prevent the jaws 42a from rotating on the die 44a, the latter is provided at its ends with keys 45 fitting into slots 47 in said jaws, thus the recesses 46a in said jaws are retained in proper position to permit the lowe1 portions of the jaws to pass beneath the bottom of the ladle 2a and engage the open ends of the bearing to be babbitted.

The modified form also differs from the preferred form, in that gates 441 are formed in the die 44, so that the molten metal in flowing from the open bottom of the ladle 2fl will pass through said gates to the lower portion of the bearing. rllhe gates 44" have seats 44C to receive the lower ends of the valve plugs 8a which when set eut off the flow of molten metal through the die 44a. rhe upper ends of the valve Vplugs 8 have pin-and-slot connections 8" with an equalizing member SC having a pin-andslot connection Sd with the valve rod 1.0%
